Halo 3
Equal-start fights reward predicting humans

Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.

Known maps, minimal randomness beyond spawn waves
Halo 3
Equipment pickups and spawn variation

Halo 3
Power-weapon timers and map control
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
